Abstract

The utility model discloses a bobbin release preventive device, which comprises a support plate and an expansion plate. A torsion spring positioning shaft and an expansion plate guide block are fixed to the support plate, a torsion spring is sleeved on the torsion spring positioning shaft, one end of the torsion spring is inserted into a torsion spring insertion hole on the support plate while the other end of the torsion spring is inserted into a torsion spring insertion hole on the expansion plate, a guide groove is disposed on the expansion plate, one end of the guide block of the expansion plate is inserted into the guide groove, the guide groove is longer than the guide block of the expansion plate, and the guide block of the expansion plate can be in sliding fit with the guide groove in a translation manner. The bobbin release preventive device prevents a bobbin from releasing from a bobbin gear, and ensures no release of the bobbin at high speed.

Description

The bobbin anti-bouncing device

Technical field

The utility model relates to a kind of bobbin device, relates in particular to a kind of roving bobbin anti-bouncing device.

Background technology

Thereby Speed frames bobbin gear drives bobbin and rotate to realize reeling roving to bobbin in spinning process, and the bobbin gear band bobbin and moved up and down and make rove be aligned on the bobbin uniformly simultaneously.Present technology is that upper end and the bobbin endoporus bottom that the bobbin lower surface is put into the bobbin gear is enclosed within on the cylindrical on bobbin gear top, make bobbin to rotate around the axis of bobbin gear and to move up, simultaneously installation tube barrel bolt 7 cooperates with the radial slot 8 of bobbin bottom and makes that bobbin can not be around the axis rotation of bobbin gear on the bobbin gear, and have only the free degree upwards not retrain, this is because bobbin whenever doffs all to be needed to change, if there is constraint can cause workload to increase.But at the spinning initial stage because ingot speed is high, when the bobbin gear be changed to by moving upward with down rail move downward after, before spinning during which floor yarn, because bobbin adds that pulling force that the deadweight of rove can not overcome yarn the Speed frames bobbin can occur and break away from the bobbin cogwheel phenomenon and be commonly called as " jumping pipe ", cause broken yarn, can't continue spinning, therefore need a kind of convenient technology that can prevent to jump pipe again of using in the industry.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, a kind of more change of bobbins that do not influence when Speed frames are stopped is provided, and after bobbin arrives certain speed, the constraint of the easy on and off degree between bobbin and the bobbin gear can be lived, solve bobbin and jumped the bobbin anti-bouncing device of managing a difficult problem.

Bobbin anti-bouncing device of the present utility model, it comprises gripper shoe and expansion plate, on described gripper shoe, be fixed with torsion spring locating shaft and expansion plate guide pad, on described torsion spring locating shaft, be set with torsion spring, insert in the torsion spring jack of expansion plate in the torsion spring jack that inserts on the gripper shoe of described torsion spring and its other end, on described expansion plate, have gathering sill, one end of described expansion plate guide pad is inserted in the gathering sill, described gathering sill length greater than expansion plate guide pad length and expansion plate guide pad can with described gathering sill mutually translation be slidingly matched.

Advantage of the present utility model: when the bobbin gear does not change or speed when low, the power that torsion spring can withdraw the bobbin gear for one of expansion plate, make expansion plate one end withdraw, do not influence more change of bobbins, when rotating, the bobbin high-speed gear can make an end of expansion plate stretch out the bobbin gear grooved on bobbin gear top by centrifugal force, insert in the bobbin cannelure, bobbin can't break away from the bobbin gear, and bobbin is not jumped pipe when guaranteeing high speed.This apparatus structure is simple, and effect is remarkable, and is easy to implement.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in detail.

Bobbin anti-bouncing device of the present utility model as shown in drawings, it comprises gripper shoe 2 and expansion plate 5, on described gripper shoe, be fixed with torsion spring locating shaft 3 and expansion plate guide pad 6, on described torsion spring locating shaft 3, be set with torsion spring 4, insert in the torsion spring jack 51 of expansion plate in the torsion spring jack 21 that inserts on the gripper shoe of described torsion spring 4 and its other end, gives the power of 5 one retractions of expansion plate.On described expansion plate, have gathering sill 52, an end of described expansion plate guide pad be inserted in the gathering sill 52 and can with described gathering sill mutually translation be slidingly matched.

Bobbin anti-bouncing device installation and application is as follows:

Gripper shoe 2 is connected on bobbin gear 1 inwall direction setting that gripper shoe normal conditions lower edge is vertical with described bobbin Gear axis.Open bobbin cannelure A1 plugging together mutually on the bobbin A inwall circumferencial direction of cooperation place with described bobbin gear, with the bobbin gear of described bobbin cannelure opposite position on open a bobbin gear grooved 11, an end of described expansion plate can be inserted in the described bobbin cannelure and can be by described bobbin gear grooved withdrawal by described bobbin gear grooved.One end of expansion plate guide pad 6 can be made of bonding guide pad shape, gathering sill 52 length make an end of expansion plate 5 can stretch out the bobbin gear grooved on bobbin gear top by centrifugal force when the bobbin high-speed gear rotates greater than expansion plate guide pad 61 length, satisfy at low speed simultaneously or when stopping in the end withdrawal bobbin gear of expansion plate 5.

Torsion spring jack 21 on the preferred gripper shoe 2 can make that the torsion of torsion spring is adjustable for a plurality of.

This device in use, when the bobbin gear does not change or speed when low, the power that torsion spring can withdraw the bobbin gear for one of expansion plate makes the withdrawal of expansion plate one end to be retracted mode shown in Figure 2, does not influence the replace tubes operation when doffing.When rotating, the bobbin high-speed gear can make expansion plate one end stretch out the bobbin gear grooved on bobbin gear top by centrifugal force, insert in the cannelure A1 of bobbin A, be the state that stretches out shown in Figure 3, bobbin can't break away from the bobbin gear, and bobbin is not jumped pipe when guaranteeing high speed.
